We present an easy and straightforward synthesis of 3-arylpiperidines by Grignard addition of piperidin-3-one with different arylmagnesium bromide reagents and acidic dehydroxylation of the resulting tertiary alcohol with the combination of triethylsilane and boron trifluoride etherate. This facile strategy was further used to synthesize preclamol. A highly regioselective dehydration of 3-arylpiperidin-3-ol
我们提出了一种简单直接的 3-芳基哌啶合成方法,方法是通过格氏加成哌啶-3-one 与不同的芳基溴化镁试剂,并与三乙基硅烷和三氟化硼醚合物的组合对所得叔醇进行酸性脱羟基。这种简便的策略被进一步用于合成 preclamol。研究了3-芳基哌啶-3-醇与三氟化硼醚合物的高度区域选择性脱水制备3-芳基-1,4,5,6-四氢吡啶骨架。还研究了一种新型二氧化硒介导的 3-芳基-1,4,5,6-四氢吡啶的二氢过氧化反应。
